Claims.

This invention relates to weight demarcating and fractional hour rateindicators for use in conjunction with the indicator of dial scales.

One of the objects of the invention is to provide 5 a simple andefficient device, which is portable from one scale to another andreadily attachable to the dial glass over the outer end of the indicatorshaft, and adapted to be located at any desired arc in the dialgraduations.

Another object is to provide an indicator device formed of wire into asector and having its arcuate section provided with a plurality ofadjustable indicating pointers adapted to co-o-perate with the dialgraduations within the wire 16 are of the device.

Another object is to provide the wire sector with means for holding itin any position desired over the dial comprising spaced arms carrying acounter balance at its lower end.

In order that the nature of my invention may be fully understood, I haveillustrated certain embodiments of the invention in the accompanyingdrawi in which:

Figure 1 is a vertical elevation of the device as applied to the dialglass of a scale and showing a preferred form of my invention, shown inuse as a demarcating indicator.

Figure 2 is a vertical section on the line 2-2 of Fig. 1, showingparticularly the position of the sector and pointers and the attachingmeans or cup.

Figure 3 is a vertical elevation of the device showing particularly theadjustable pointers and the counterbalance with the sector shown indotted outline, in use as a fractional hour rate indicator.

Figure 4 is a side elevation of one of the pointers.

In the drawing I designates a portable wire frame or sector which isprovided with an upper arcuate portion 2, converging side portions 3,and spaced extended arms 4-, formed preferably of one piece of wire andsecured by its ends to a circular counterbalance 5. There is mounted atthe converging point C a circular plate 6, upon which is disposed aknurled thumb screw I mounted on a threaded bolt 8 extending through anopening 9 in the plate 6 and secured in a bushing 9a attached to arubber suction cup to located below the plate 6 andplaced upon the dialglass G on an axis substantially concentric with the axis of theindicator shaft l l of the indicator I.

The threaded bolt 8 extends between the upper ends of the spaced arms 4,which are held between the plate 6 and the fiat top 12 of the suctioncup l0, while in use the thumb screw 1 is loosened and the sector I isswung tothe desired position with relation to the selected graduations13 on the dial D and the sector clamped securely 5 between the plate 6and the suction cup Ill by adjustin the thumb screw 1. Thecounterbalance 5 serves to hold the sector I in its adjusted positionwhile the sector is being swung into position. 10

In order to provide means for indicating or demarcating the range ofweight graduations' it is desired to locate on the dial D the arcuateportion 2 of the sector I is provided preferably with a series ofadjustable spring tension pointers or '15 markers |4a-l4f slidablymounted on the arcuate wire portion 2 and preferably formed of loopedmetal clips I5, the loop portion l6 of which grips the arcuate wireportion 2 and holds the pointers Ma-Mf in a fixed position wherever 20placed.

As an example of the practical use of the device the requirement may betoadd 200 pounds of material or liquid, as the case may be, tocontainers of a variable tare weight. In this case 25 the sector I wouldbe placed in position over the dial glass G, setting two pointers, onepointer 14a set at zero and the other pointer 14b at 200 pounds. Thenthe empty container is placed on the scale and the sector I is moved sothat the 30 first pointer 14a will meet the indicator I, forexample at200 pounds, Fig. 1. As thus set it is only necessary to add the desiredquantity of 200 pounds of material or liquid to the container so as tomove the indicator I to register with the 5 pointer Mb. When used toindicate the fractional hour rate of flow of materials of liquids from afeeding apparatus the movable pointers Mo to Me are first placed, forexample, at the scale graduations of 0-200400600 and 800 40 pounds, Fig.3, the pointer 14 and any others that may be added to the sector beingadapted for indicating other fractional hour rates of flow desired, asfor example 10 minute periods. Then the pointer I la is moved from thezero position 45 to the prevailing or registered graduation position ofthe indicator on the dial D, Fig. 3. Thus the quarter hour rates of floware automatically marked for visual observation and notation for thefollowing full hour. If indications at other fractional parts of thehour are desired, the pointers are set accordingly on the sector I.

While the preferred embodiment of the invention herein shown anddescribed is well adapted to fulfill the objects of the invention, it isto be 55 understood that it is not intended to confine the invention tothe precise form of construction herein disclosed, for it is susceptibleof modification in various forms, all coming within the scope of theinvention.
